Elkem Carbon Slovakia a.s.

Elkem Carbon Slovakia is located in the town of Žiar nad Hronom, in the Banská Bystrica Region in the centre of Slovakia.

History of the plant

Established in 1954 at a primary aluminum producer site, Elkem Carbon Slovakia’s sole objective was to produce Søderberg anode paste.

In the 1990s, significant investments were made for Søderberg electrode paste and ramming paste production. In the same period, they also expanded recarburiser production for steel and foundries. In 2005, the aluminium plant shifted to prebaked anodes, discontinuing anode production.

The EURO project (2012-2015) was initiated to upgrade the plant with new filtration systems, packing lines, cooling systems, software, and laboratory equipment.

Elkem ASA acquired the business on the 1st of June 2023.

About products

The plant is equipped with two rotary kilns, for high temperature treatment of various black raw materials, including the production of gas calcined anthracite.

Multiple gas calcined anthracite grades are produced as recarburizers or as intermediate product used in the production of electrode pastes and ramming pastes. This involves blending calcined anthracite and petcoke with coal tar pitch or other binders based on product and use.

The mixing-and-blending plant is equipped with eight sigma mixers, for the production of various qualities of Søderberg electrode paste and ramming pastes.

Our recarburizers products ranges from 100% gas calcined anthracite to various gas calcined anthracite and calcined petcoke blends.
